Do you know. the drill bit in cutting the hole in the glass can be done in just half an hour. It will be based on the movie glass cutter fixed in the slot on the end of the steel rod. Its diameter should be slightly smaller than the diameter of the roller.
The roller is mounted on the holder by a rivet, and so he did not have the ability to rotate. Now mount the drill bit in the drill and
you can drill into the glass hole.
